Bus Travel Now and Then Nobody, except perhaps little children, considers a journey in a bus as exciting experience. Although there are thousands of cars on the roads, more people travel by bus than by car. Workers rushing to their offices or factories, children hurrying to school, housewives going shopping, use buses. For cities without other public transport services, if all the buses were to stop running for a day, work would come to a standstill in hundreds of offices and factories and most classrooms would be deserted. Buses today are large and have comfortable seats, mostly facing the front. To get the driver to stop at a bus-stop, a passenger has merely to push a button, which rings a bell placed near the driver. The bus schedule for the city is well planned, and seldom do A. One may be forced to leave the bus. B. One may not have to pay the fare. C. One may become suffocated. D. One may lose one’s balance.

For the latest on the pursuit of the American Dream in Silicon Valley, all you have to do is to talk to someone like "Nagaraj"(who didn’t want to reveal his real name). He’s an Indian immigrant who, like many other Indian engineers, came to America recently on an H-1B visa, which allows skilled workers to be employed by one company for as many as six years. But one morning last month, Nagaraj and a half dozen other Indian workers with H-1Bs were called into a conference room in their San Francisco technology-consulting firm and told they were being laid off. The reason: weakening economic conditions in Silicon Valley, "It was the shock of my lifetime," says Nagaraj.
^This is not a normal bear-market sob story. According to federal regulations, Nagaraj and his colleagues have two choices. They must either return to India, or find another job in a tight labor market and hope that the Immigration and Naturalization Services (INS) allows them to transfer their visa
